Don't know. He must do because he's been through the process before and he still bowls with a bent arm.
Depends on whether you consider merely breaking the rules to be cheating. I don't. For mine there has to be malicious intent and I find it extraordinarily difficult to believe that a guy who has been through the process would continue to chuck every ball thinking that he wouldn't get pulled up again. The fact he has and does suggests stronger evidence for something he can't help than him maliciously chucking every ball thinking that it won't get noticed or that he won't get in trouble. Unless he's into self-sabotage.........
I think we all need to re-examine exactly what the chucking legislation is designed to prevent. For me, because most can throw a ball faster than they can bowl it, it's designed to prevent injury and people who are ordinarily not very quick from throwing lethal-speed deliveries. Shabbir, from what I've seen of him now and in his early career, bowls at largely the same pace whether his action is doubtful or not. It's not as if he's a medium-pacer running around injuring batsmen with vicously pinged faster balls. A lot of the evidence points towards him being a guy who has a physical problem he has difficulty correcting. Now, whether it really is not-fixable or whether he's been lazy with his rehabilitation in strengthening the muscles around his albow which would prevent him from chucking I don't know but it really does defy logic to suggest he's a deliberate pinger who thought he wouldn't be caught doing his dirty deeds because if tehre's one guy who's been the subject of more scrutiny that Murali since his career began, it's Shabbir.
I dunno, I just figure a guy like Shabbir needs continuous monitoring and remedial work, not punishment.
As long as he's not just left on his own and forgotten about then yes, I have no problem with him not playing until his action passes scrutiny. But then, for that reason, he shouldn't be playing any cricket (not just international cricket) until this happens. I just hope he receives the support he needs, like Lee, Shoaib and Murali before him but I don't hold out much hope.
